Policy Based Dynamic Negotiation for Grid Services

Abstract

Policy-based dynamic negotiations allow more flexible authorization in complex Grid environments, and relieve both users and administrators from up front negotiations and registrations. This paper describes how such negotiations overcome current Grid authorization limitations, and how policy-based negotiation mechanisms can be easily integrated into a Grid infrastructure. Such an extension provides advanced access control and automatic credential fetching, and can be integrated and implemented in the new version 4.0 of the Globus Toolkit
